Create an new installation with V11.2.2 on a shared webhoster

[Zarch (Mick Wall)]

Ubuntu 22 uses PHP 8.1.2
EmonCMS needs v7.4.3

I’d suggest installing ubuntu 20, not 22.

Error after new installation - Proxmox

I upgraded a Ubuntu 20 LTS VM to 22 LTS and it seems to remove old php versions (7.4.3 in my case) and plonk 8.1.2 on there. So I would imagine any brand new 22 LTS would be 8.1.x out of the box. This obviously broke emoncms, so I reverted and left it as is for now.
